SPECIFICATION farming part of Letters-raten@ No. 679,862, dated August e, 1901. Application iiled October 23, 1900. Serial No. 34,094. (No model.)

at Fitch Bay, in the Province of Quebec, Can' ada, have invented new and useful Improvements in Acetylene-GasGenerators, of which the following is a specification.

This invention relatesA to new and useful improvements in acetylene-gas generators, and is more particularly an improvement upon Letters Patent granted to David L. Baumgarten May 8, 1900, No. 648,910.

The invention has for its object to provide `means of novel construction whereby the carbid may be fed in equal quantities to the generator automatically as soon as the supply of .gas within the bell of the gasometer is about exhausted, said feed being operated by the up-and-down movement of the said bell.

A further object is to providereceptacles for the carbid which are provided with hinged air-tight bottoms adapted to open automatically when brought to a fixed position above the hopper of the generator.

Another object is to provide means in the feeding-slide for controlling the escape of gas arising from the first contact with Water of the carbid `While on its way to the generator.

Another object is to so construct the interior of the generator as to prevent the carbid from mixing with the slaked material upon the bottom of the receptacle until after all th gas hasl been evolved therefrom.

Another object is to provide a gasometer whereby a minimum amount of Water will provide sufticient water seal, and thereby reduce the Weight of the apparatus and facilitate its iilling.

Another object is to provide an alarm adapted to ring automatically when the bell of the gasometer approaches the downward limit of its movement.

Another object is to provide a device to tilter the gas while passing from the generator to the gasometer.

Another object-is tofprovide a device to close all communications between the gasometer and the generator while emptying and reiillin g the generator and so arranged as to prevent the escape of gas from the gasometer.

Another object is to provide adevice, in

combination with a check or stop dog, con# ometer.

trolling the movement of the carriage carrying the carbid-holders.

Theseobjects are attained by combinations of parts described in the general description.

Rollers are journaled upon the side of the gasometer and support a circular carriage having brackets secured upon the upper surface thereof at regular intervals. Each bracket supports a receptacle of particular construction having a hinged bottom, which Vis adapted to be opened automatically when the same arrives at a fixed position above the hopper. Said brackets also provide teeth or studs and are arranged upon the carriage at regular intervals, adapted to be contacted by a dog which is pivotally mounted at one end of a bell-crank lever., This lever is pivoted to the body of the machine and is adapted to be swung upon its pivot .by the up-and-down movement of the bell of the gasometer. Suitable means are also provided for controlling the movement of the carriage. A hopper is arranged at one side of the gasometer and is provided with a valved outlet opening into the generator, saidhopper being adapted to discharge the material admitted thereto upon a screen suitably located at a point therebeloW. A tube extends upward from the bottom of the gasometer and is provided at the lower end with a valve of peculiar construction which is opened and closed by means of a crank or other suitable device located upon the outer side wall of the generator. On top of that tube, being in the gasometer, is a fil ter, catching all dusts that maybe carried by the gas.

The invention also consists in the further novel construction and combination of parts, which will be hereinafter fully described, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure l is a side view of a vertical section of a machine embodying my invention and in which form the generator is outside the gas- Fig. 2 is a vertical section f a machine embodying myinvention, in which form the generator is under the gasometer. Fig. 3 is a horizontal cross-section of valve S, Fig. 2, at line B C. Fig. 4 is a top view of a machine embodying my invention. Fig. 5 is a detail side view of a portion of the carriage,

f Referring tothe drawings, in which similar ligures refer to similar parts throughout thel p casing and is covered with a cap 4, Figs. 1, 2, and 4, `which extends thereover, and the A partition 2, Fig. 2, which .is inclined u-p-l ward toward the center, is arranged within the cylindrical casing ata point between the ends thereof, vand fitted at 'the center of this 1 partition is a tube 3, Fig. 2, which extends upward to a point above the upperl end of the edges ot' which are a t'rie over the surface of the water contained within the gasometer.

- l ner inclined surface 7, Figs( 2 and 3, thereof' -Said cap4 is surrounded by an elastic' fabric, which forms-a circular apron 5, iioating-on the water in the gasometer, the under surface of which apron is villous, provided with 5 suitable fibrous pendants 6,through which the gas isy forcedand consequently filtered.

inclined inwardly at the lower end, the in'- forming a bearing for the valve 8, which is su bstantially of the form of an inverted frustum of a cone. This valve is provided in the sides thereof with slots 9, which are adapted to register with vsimilar slots formed Within the inclined lwall 7 of the tube.

rA bracket 10 extends downward from the bottom of the tube 3 and serves as a bearing forthe shaft 11, the opposite end of `which is journal'ed within the casing 1 and is provided with a crank 12 or other device, whereby the same may' be readily revolved. pinion 13 is mounted upon this shaft 11 and meshes with the teeth formed upon an inclined curved strip 14, which is secured at the outer end of an arm 15, fastened to the bottom of the valve 8. It will thus be seen that when the shaft 11 is revolved the pinion 13 will cause the strip 14 to swing to one side of the arm 15, carrying the valve therewith and` causing the slots thereof to move into or out of register with the slots in the tube. l

A tube 16 extends downward from the top of the bell of the gasometer, and anv eX- haust-pipe 17 extends thereinto and is pro-V vided with an outlet, which is arranged at any suitableV point. arranged within the gasometer and extends from the center of the bell, over the cap 4, above the water-level therein to the point or points of use.

Formed upon 'the outer side of the casing at a point above the partition 2 is a preferably rectangular chute 19,the bottom of which is inclined, as at 20, and communicates with the generator at a point near the top thereof. The inclined bottom 2O of the chute extends for a suitable distance into the generator and terminates at apoint above awire screen 21 lA supply-pipe 18 is also I j the opposite sides of .the generator. chute19 is provided at itsupper end Withan which is hung from brackets 2x2, piv'oted to l outlet 23, which may be connected by a suitxable pipe (not shown) to the `outside of the i building and is adapted to permit of the escapeof gas generated within the chute. A hopper 24 ismounted upon the side of the chute 19. A gate 25 is pivoted within the vchute 19 at a point 26 above. the inlet thereto and extends downward over said inlet and normally closes the same, beingheld in such position bygravity. A suitable' drain 27 is arranged withinrthe bottom of the generator,

r as shown.

Extending from the sides ofthe casing 1 of the'gasometer, Figs. 1, 2, and 4, at regular inter- Vals and near tothe upper edge 28 are studs 29, upon which are journaled grooved wheels 30.` i lar carriage 31, havingrbrackets 32 extending at regular intervals from the upper surface at the inner and outeredge of therail 31, respectively, the outer end of brackets engaging loops 33, formed upon the inner faces of vThe bottom of the tube 3 is enlarged and f ing a rim to hold a packing-ring 36, and which bottom is hinged to the side ofthe receptacle A beveled l 34 which first arrives at the hopper when the carriage is in operation. This bottom is adaptled to be held closed by a catch 37, which is i hinged to the side of the receptacle 34 farthest 1removedfrom the vhinge thereofsaid catch engaging in the'end of a spring 37', riveted to the bottom 35. The catch isprovided with a tongue 3S, which extends downward into the path of the hopper.

On top of the gasometers` bell is a ring 39, Figs. 2, 4, and 5, to whichv is hooked the end of a lever 40. At one endof thev lever 40 is a sleeve 41, which slides with the up-anddown movement of the bell along thevertical rod 42. When the bell and the sleeve 41 come down, said-sleeve rests upon the adjustable index 43, carries it down with the vertical rod 42 and through the bell-crank 1ever 44, which is pivoted at 45,0n the side of the water-tank, and raises the dog 46 by means of a rod 46a, thereby releasing the carriage 31. `At the same time the bell-crank lever 44 will move the dog 47 forward into contact with the `bracket 32 and set the carriage 31 in motion. The retaining-dog 46, which is raised after the dog 47 has moved the carriage partly forward, is pivoted to the watertank' and is so arranged as to normallypre- `vent movement ofk the carriage in one direction, Vwhile the dog 47 prevents movement thereof in the opposite direction.

I preferably provide means for sounding an alarm when the gasometer-bell passes the dumpingmarh, the means shown in thcdraw- The Mounted upon these wheels is a circu- IOS IIO

but insulated therefrom. These springs form part of an electric circuit, which includes an alarm-bell, (not shown,) andare adapted to be pressed together (to complete the alarmbell circuit) by the contact therewith of the arm 48.

Operation: Through the funnel 50, Fig. 2, the generator l is filled to near the top of said funnel, which will raise the water-level a triie over the valve 8. The gasometer 1 Figs. 1, 2, and 4, is filled with water to a little below the edge 28, filling the bell to the dotted line D E and plunging in the water the ends of the bristles of the brushy filter 6. Carbid is placed within each of the receptacles 34 and the same closed by forcing the covers until engaged by the catches 37 and then are hung to the outer brackets 32. Carbid is then admitted to the hopper 24, and the weight thereof will force the gate 25 open and permit the material to fall upon the inclined bottom 20 and thence upon the screen 21 within the gasometer. The carbid will iirst contact with the water, then fall upon the screen 21, and after the same has been completely slaked it will sift through the openings in the screen and fall to the bottom of the generator. The gas generated will rise within By the fiange 51 it will be prevented from going into the chute 19 and will be directed by the inclined partition 2 toward the valve 8. This valve has been previously opened, and as the gas generated will pass through the slots 9 therein and in the wall of the tubeanvd up through saidA tube into the cap 4 the cap will direct the gas down below the apron 5 and be forced through the filter 6 and then into the bell of the gasometer. The bell will then rise, and should too much gas be generated the surplus will escape through the exhaust-pipe 17. As the gas is drawn away from the bell through the pipe IS the same will gradually lower and the lever 40 and sleeve 41 will be carried downward therewith. Then the sleeve 41, coming in contact with the index 43, will press down the rod 42, which through the lever 44 will work the dogs 46 first, then 47, and move forward the carriage 31. This carriage will be carried such a distance at each operation of the dog 46 as to bring one of the receptacles 34 to a point above the hopper 24. As the receptacle passes into position over the hopper' the tongue 38 of the catch 37 will contact with the edge of said hopper and be forced ontward from engagement with the spring 37 ofl the bottom 35. Said bottom will then promptly swing downward and discharge the contents of the receptacle into the hopper, and the operation of the device will be repeated upon the next operation of the dog 46. As soon as the bell of the gasometer is moved upward by the gas therein the bell-crank lever will swing backward toits normal position and cause the dog 47 to engage with a bracket 32, adjacent to the one last moved forward.

While I have shown the gasometer and generator formed one above the other within one casing, I do not limit myself to this construction, butif desired, may Darrange the generator at a point without the gasometer. I have shown this construction in Fig. 1. shown in said figure, the generator 52 is provided with a valve 53 and a tube 54, which extends from the top thereof and which communicates with a Washer or trap 55. The hopper, which is substantially such as hereinbefore shown and described, communicates with the generator, and carbid-receptacles are mounted either upon the casing of the gasometer or on the generator and operate in the same manner as before described. The pipe 54 is connected by means of a second pipe 56 with the interior of the gasometer. Said gasometer comprises an inner casing 57, which extends upward into the bell, thereby permitting the use of a minimum amount of water and reducing the weight of the apparatus. All the other parts of said gasometer, Fig. 1, are the same as in Figs. 2, 4, and 5. In the generator 52, Fig. 1, the cut-0E valve 53 is to permit the generator to beemptied. A bib-cock 58, Fig. l, in the Side of the generator 52 is to draw olf separately from the residuum the upper portion of the water which is supposed to be clean.
